Well no... Do not add or remove them to the missing list, just put them in a sub-section named "need revision confirmation" for example.
Like in the USA list, with the game "Disney Frozen: Olaf's Quest *Nintendo Selects*". We just need to confirm their revision first to be sure that they are undumped. Without that info, it's too early to put them in a missing list.
Dunno how to be more clear lol. Can someone help to explain xD
